In the 1700s Emanuel Swedenborg, Immanuel Kant, and Pierre-Simon Laplace independently thought of a rotating gaseous cloud that cools and contracts in the middle to form the sun and the rest into a disc that become the planets.

This theory failed to account for the distribution of angular momentum in the solar system.

planetesimal hypothesis involving a star much bigger than the Sun passing by the Sun and draws gaseous filaments from both out which planetesimals were formed;
